ABSTRACT:
An improved high-intensity rotary peening particle support of the type having a plurality of peening particles metallurgically secured to an exposed face thereof is presented, the support having a base composition consisting essentially of from about 0.08 to about 0.34 weight percent carbon, the balance iron, and a Ni-enriched layer which provides a hard, wear resistant surface. A method of producing such a support is also described, the method including cold forming a peening particle support base composition as described, stress relieving, brazing peening particles to an exposed face of the support, austenitizing, quenching, and tempering the support to form a support having a Ni-enriched layer which is harder than the base composition.
